Chemfluor® PTFE Fluoropolymer Helically Convoluted Inner Tube
Polypropylene Braid
Open Pitch

Features and Benefits

Chemfluor® PTFE inner tube
Polypropylene braid
  • Ultraviolet stabilized
  • Offers good chemical resistance against many types of acids
  • Resists abrasion better than stainless steel reinforcements
  • Lightweight, with minimum force to bend
    -Easy to transport, connect and disconnect
    -Less strain on adjoining equipment/scales
  • Braid fraying minimized, reducing risk of hand injuries from wire braid punctures
  • Does not conduct internal heat as readily as stainless steel braided hoses
  • Burn potential from incidental contact greatly reduced

Pressure Rating

N/A Burst Pressure ratings at ambient 70ºF (21ºC). See below on vacuum/pressure ratings at temperatures other than ambient.
Working Pressure is given at room temperature. Decrease working pressure to 40 psig for all sizes above 175ºF.
Vacuum Rating all sizes: 29.9" Hg @ 70ºF. Decrease working pressure rating 1% for every 2ºF above 150ºF. 1-1/4" rated @ 26 Hg; 1-1/2" rated @ 24" Hg; 2" rated @ 20" Hg when installed less than 2X minimum bend radius.

  • 1 Working Pressure is given at room temperature. Decrease working pressure to 40 psig for all sizes above 175ºF.
  • 2 Burst pressure ratings at ambient 70ºF (21ºC). See below on vacuum/pressure ratings at temperatures other than ambient.
  • 3 Vacuum Rating all sizes: 29.9" Hg @ 70ºF. Decrease working pressure rating 1% for every 2ºF above 150ºF. 1-1/4" rated @ 26 Hg; 1-1/2" rated @ 24" Hg; 2" rated @ 20" Hg when installed less than 2X minimum bend radius.
